BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates generally to an apparatus and method forconfiguring and opening product packaging and more particularly to anapparatus and method for labeled packaging and an easy method forremoval of the labeled packaging from the product.

2. Description of the Prior Art

Product packaging can be difficult to apply and remove depending uponthe type of packaging that is preferred for use with the product.Packaging that seals the product can be both onerous and complicated toremove or separate it from the product. Peel wrap, for example, isapplied to shrink wrap packaging and functions as an opening feature forthe customer or end-user to use to remove the product packaging. Thisand many other current features used to assist in opening shrink wrappedproduct are widely viewed as unnecessarily complicated and unreliable.

It is therefore desirable to provide a cost efficient and effective wayto configure the packaging and labeling on a product to aid in theremoval of packaging from the product.

It is further desirable to provide reliable packaging that is easilyremoved.

It is further desirable to provide product packaging for pressed solidproducts that is configured for easy removal and separation from thepressed solid product.

SUMMARY OF THE INVENTION

In one embodiment, the invention is a method for removing packaging froma product. The method includes providing a product in a packaging havinga label covering a predefined failure point in the packaging. The stepsinclude lifting the label from the packaging to tear open the packagingstarting at the predefined failure point and separating the packagingfrom the product. In a preferred form, the lifting step includesseparating a portion of the label from packaging around a portion of thepredefined failure point without tearing open the packaging. Forexample, lifting in one direction prevents tearing of the predefinedfailure point in the packaging thereby permitting reapplication of thelabel and preservation of the packaging while lifting in anotherdirection tears open the packaging.

In another embodiment, the invention is labeled product packaging. Thepackaging is shrink wrap packaging that is adapted for sealing around aproduct. A predefined point of failure is configured in the packaging.The predefined point of failure has a failure mode for when pulled in atleast one direction away from the packaging. A label is secured to thepackaging in covering relation over the predefined point of failure. Thelabel is also sealed to the packaging and adhered to the predefinedfailure point. In a preferred form of the invention, the product is ablock of solid detergent, and the predefined point of failure is a cutthrough the packaging in the shape of an “X”, a crescent or a “V”.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Product packaging can encompass use of numerous types of packagingenclosing various types of product. In one aspect of the presentinvention, shrink wrap is used as a product packaging 10 as illustratedin FIGS. 1A-B for enclosing a product such as a pressed solid or castblock of detergent. The product packaging 10 can include one or morelabels 12 positioned on one or more surfaces of the product packaging10. For example, label 12 could be positioned on a top or bottom face ofthe product packaging 10 as illustrated in FIG. 1B or on a front or backface of the product packaging 10 as illustrated in FIG. 1A. Labelingcould also be printed directly onto the product packaging 10. Theproduct packaging 10 generally assumes the shape of the enclosedproduct. For example, as illustrated in FIGS. 1A-B, the productpackaging 10 has a peanut shape as a result of the enclosed productbeing peanut-shaped. Thus, labeling such as label 12 illustrated inFIGS. 1A-B may be positioned on a surface of the product packaging 10that is generally planar or non-planar. Because the product packaging10, such as shrink wrap, follows closely the contour or outer surface ofthe enclosed product, removal of the product packaging 10 can becomplicated and difficult. Furthermore, it is important that the productpackaging 10 remain sealed until the product is used. What follows is adescription of the invention which allows for easy removal of theproduct packaging 10 and access to the enclosed, sealed product.

In one aspect of the invention, the product packaging 10 includes alabel 12 applied to the packaging after it is sealed around an enclosedproduct. For example, in the case of the product packaging being shrinkwrap, the shrink wrap and enclosed product are run through a heat tunnelprior to label application. The label 12 may include various forms ofinformation, artwork, company marks, branding, product ingredients anduse suggestions, source or manufacture of the product, and instructionsfor removing the packaging 10 or reapplying the label 12. The label 12is adhered to the surface of the underlying product packaging 10 using alight or medium grade adhesive as is further defined below.

In one aspect of the present invention, after the product packaging isapplied so as to enclose the product and before the label 12 is adheredto the product packaging 10, a predefined point of failure 14, 16 or 18as illustrated in FIGS. 2A-C is configured in the product packaging 10.For example, in the case where the product packaging 10 is shrink wrap,the shrink wrap and the enclosed product are run through a heat tunnelbefore the predefined point of failure is formed in the productpackaging 10. Making the predefined point of failure after heattunneling minimizes label 12 alignment and cutting issues relating toformation of the predefined point of failure.

FIGS. 2A-C illustrate exemplary embodiments of a predefined point offailure 14, 16 and 18 of the present invention. For example, asillustrated in FIG. 2A, the predefined point of failure 14 is generallyan “X” shape. The predefined point of failure 14 may be formed bycutting the product packaging 10 in the desired shape, perforating theproduct packaging 10 in the desired shape or generally weakening thematerial of the product packaging 10 in a desired shape. In FIG. 2B, thepredefined point of failure 16 is formed in a crescent shape and in FIG.2C the predefined point of failure 18 is formed in a horizontal “V”shape. In each instance, the predefined point of failure may be formedby a cut passing through the entirety of the product packaging 10, aperforation of the product packaging 10 or a weakening of the productpackaging 10. FIGS. 2A-C illustrate some exemplary shapes and geometriesof a predefined point of failure. The present invention contemplatesthat other shapes and/or geometries may be used to form a predefinedpoint of failure in the product packaging 10. For example, thepredefined point of failure could be an oval, “U”, or rectangular shape.Depending upon the desired functionality, certain shapes may achieve theobjections of the present invention better than others as describedbelow.

As shown in FIGS. 2A-C, label 12 is positioned and adhered to theproduct packaging in covering relation over the predefined point offailure 14, 16 and 18. By encompassing the entire predefined point offailure, the label 12 acts as a protective mechanism that prevents dirt,moisture, or other contaminates from contacting the enclosed productthrough the predefined point of failure. Thus, the label 12 adheres tothe product packaging 10 and the predefined point of failure to seal thepackaging to protect and preserve the enclosed product.

As indicated, the predefined point of failure may be formed in theproduct packaging 10 by a cut passing through the entirety of theproduct packaging 10, a perforation in the product packaging 10 orintermittent cuts in the product packaging 10 formed in the shape of thepredefined point of failure. The predefined point of failure may alsoinclude a weakening of the product packaging 10 in the shape of thepredefined point of failure. FIG. 3 illustrates one example taken fromthe predefined point of failure 16 illustrated in FIG. 2B. In FIG. 3,the predefined point of failure 16 is cut into the product packaging 10and forms a crescent shape. The crescent shape is used here as anexample since the following configuration could be applied to the othershapes discussed and considered above. The cut extends through theproduct packaging 10 to form the shape of the predefined point offailure 16 with the exception of a portion of the product packaging thatforms tabs 20 and 22. Here, the product packaging 10 within the crescentshape remains attached to the product packaging 10 without outside thecrescent shape via tabs 20 and 22. The tabs 20 and 22 keep the productpackaging 10 within the predefined point of failure 16 generally on thesame plane as the product packaging 10 outside of the predefined pointof failure 16. The tabs 20 and 22 also allow the material within thepredefined point of failure 16 to remain taut without creating anunattended separation or gap between the product packaging 10 within thepredefined point of failure 16 and the product packaging 10 outside ofthe predefined point of failure 16. This is particularly useful in theinstance where the enclosed product has one or more non-planar surfacessuch as illustrated in FIGS. 1B and 4A. The tabs 20 and 22 help preventthe predefined point of failure 16 from adhering to a surface of theenclosed product, such as by static electricity, thereby residing in aplane or position than the product packaging 10 around the predefinedpoint of failure 16. Keeping the product packaging 10 around thepredefined point of failure 16 generally in the same plane allows thelabel 12 to adhere to the surface of the product packaging 10 and thepredefined point of failure thereby ensuring that when the label 12 isapplied to the product packaging 10, the label 12 adheres to the entireof the product packaging 10 beneath the label 12 and not just thesurface of the packaging around the predefined point of failure.

FIGS. 4A-B illustrate one aspect of the invention for forming apredefined point of failure in product packaging 10. For example, alaser cutting system 24 may be used to configure a predefined point offailure in product packaging 10. In this manner, the product is enclosedwithin shrink wrap packaging as previously discussed and moved along aconveyor 26. A positioner 32 moves and holds the product packaging 10 ina fixed distance away from the laser 28. The laser beam 30 emitted fromthe laser 28 is then used to create a predefined point of failure 14 inthe product packaging 10. The predefined point of failure, as previouslydescribed, may include a continuous cut, a partial cut, a perforatedcut, or a weakening of the product packaging 10. Positioning the productpackaging 10 a fixed distance from the laser 28 permits a fixed powersetting to be used for the laser 28 so as to not affect the enclosedproduct, particularly when cutting a predefined point of failure on anon-planar surface of the product packaging 10 as illustrated in FIG.4A. In one aspect of the invention, a laser from a lasermanufacturer/provider such as Preco, Inc. or LasX may be used to form apredefined point of failure in the product packaging 10. In anotheraspect of the invention, a heating element shaped in the form of apredefined point of failure may be used to cut or form a predefinedpoint of failure in the product packaging 10. This could include aheating element having a “X”, crescent or horizontal “V” shape. Thetemperature of the heating element could be controlled so as to controlthe cut or weakening of the product packaging 10 in order to form adesired predefined point of failure. With each of these methods, thepredefined point of failure is created in the product packaging 10before the label 12 is applied or adhered to the product packaging 10 incovering relation over the predefined point of failure. In anotheraspect of the present invention, a foil may be included or incorporatedinto a label 12 and formed in the shape of a predefined point of failuresuch as an “X” shape, crescent shape or generally horizontal “V” shape.The label 12 having the foil is then adhered to product packaging 10onto a desired surface of the product packaging 10. Here, the productpackaging 10 does not include a predefined point of failure beforeapplication of the label 12. To form the predefined point of failure inthe shape of foil, the label 12 is exposed to magnetic energy whichthereby heats the foil creating a predefined point of failure in theproduct packaging 10 beneath the label 12 and in the shape of the foil.Thus, the predefined point of failure is created in the productpackaging 10 while the label 12 is adhered to the product packaging 10.In this manner, the product packaging 10 remains sealed at all timeseven while the predefined point of failure is being formed in theproduct packaging 10.

FIGS. 5A-C illustrate exemplary aspects of the invention for removingproduct packaging 10 from product enclosed in the packaging. Aspreviously indicated, the label 12 is adhered to the product packaging10. In one aspect of the invention, a light or medium grade adhesive 34is applied to the backside of a label 12. A stronger adhesive 36 such asillustrated in FIGS. 6A-6B may be applied to the portion of label 12 incontact with the predefined point of failure to permit separationbetween the label 12 and the product packaging 10 while maintainingadherence of the label 12 to the predefined point of failure. In FIG.5A, the predefined point of failure 14 is formed in the shape of an “X”.A corner or edge of the label 12 is lifted and separated from theproduct packaging 10. As the label 12 is torn from the product packaging10, the label 12 remains adhered to the predefined point of failure 14thereby forming tears 38 and 40 in the product packaging 10 whichcontinue to propagate through the product packaging 10 while the label12 is further lifted and torn from the product packaging 10. Continuingto pull the label 12 from product packaging 10 tears the productpackaging 10 to allow the product enclosed in the product packaging 10to be separated from the product packaging 10 with ease. FIGS. 5B-Cillustrate how the product packaging 10 is opened using the crescentshape predefined point of failure 16 and the horizontal “V” shapepredefined point of failure 18. Like FIG. 5A, the label 12 is liftedfrom the product packaging 10. The predefined point of failure 16 and 18remain adhered to the label 12 thereby forming tears 38 and 40 in theproduct packaging 10 which propagate through the product packaging 10 asthe label 12 is further torn from the product packaging 10. Aspreviously indicated, the label 12 may include various types of indiciasuch as instructions on how to remove the label 12 and thereby tear openthe product packaging 10.

FIGS. 6A-B illustrate the dual functionality of certain shapes ofpredefined points of failure of the present invention. In certaininstances, depending upon the shape of the predefined point of failure,the label 12 may be removed and reapplied without opening the productpackaging 10. Also, the label may be replaced with another label withoutopening the product packaging 10. For example, in instances where thelabel 12 needs reapplied, replaced or adjusted because it was appliedincorrectly, is the wrong label or is misaligned, the label 12 may beremoved from the product packaging 10 without tearing the productpackaging 10. In FIG. 6A, the predefined point of failure 16 is in theshape of a crescent as illustrated in FIGS. 2B and 5B. Lifting the label12 in one direction as illustrated in FIG. 5B tears open the productpackaging 10; however, lifting the label 12 in the opposite directionpermits the label 12 to be separated from the product packaging 10without tearing the product packaging 10 as illustrated in FIG. 6A.Thus, in the case where the predefined point of failure is formed in thedirection in which the label 12 is peeled, the label 12 is permitted toseparate from the product packaging 10 without tearing the productpackaging 10. The label 12 then may be reapplied and used tosubsequently tear open the product packaging 10 as illustrated in FIG.5B. Similarly, in FIG. 6B, to remove label 12 without tearing productpackaging 10, the label 12 is peeled off in the direction of thepredefined point of failure 18. One or more tabs, such as tabs 20 and 22illustrated in FIG. 3 may be included in the predefined point of failure16 and 18 in FIGS. 6A-B to further prevent unintentional tearing of theproduct packaging 10 when the label 12 is peeled in the direction of thepredefined point of failure. As previously indicated, the label 12 mayinclude one or more types of adhesive. For example, a light adhesive 34may be used for generally adhering to the surface of the productpackaging 10 around the predefined point of failure whereas a strongeradhesive 36 may be used to adhere the label 12 to the predefined pointof failure itself. The bonding strength of the adhesive 36 is sufficientto maintain adherence to the predefined point of failure when the label12 is lifted from the product packaging 10 as illustrated in FIGS. 5A-C,but still permits the label 12 to be removed and reapplied as shown inFIGS. 6A-B.

In another aspect of the present invention, the product packaging may bewithout a label. In this manner the predefined point of failureconfigured in the product packaging is left uncovered. As discussedabove, the predefined point of failure may include tabs to keep it fromunintentionally opening thereby keeping the product packaging generallysealed until opened. The predefined point of failure could be also beconfigured as a perforation or by intermittent cuts passing through thepackaging. The packaging remains generally sealed until the user gripsthe predefined point of failure and begins to separate it from thepackaging. The packaging separates along the predefined point of failurefirst and then forms one or more tears that propagate into the packagingto open it. Indicia may be printed directly on the packaging indicatingto the user how to open it.
